This application, entitled “Electronic Fetal Monitoring Applications and Display,” is a continuation application of U.S. patent application Ser. No. 12/564,569, filed Sep. 22, 2009, published as US 2011/0071414 A1, issued Apr. 7, 2015 as U.S. Pat. No. 9,002,441, and entitled “Electronic Fetal Monitoring Applications and Display.” The entirety of the aforementioned application is incorporated by reference herein.

BACKGROUND

Electronic fetal monitoring (EFM) is the use of electronic fetal heart-rate monitoring for the evaluation of fetal well-being. EFM devices are used during pregnancy, labor and birth in over 99% of patients. Clinicians base clinical decisions utilizing the waveform information produced by EFM devices. EFM devices may show fetal heart rate deceleration and acceleration patterns that are monitored by clinicians. Additional information such as heart rate, blood pressure and uterine pressure and contraction information may also be monitored. This information may be used by clinicians to determine if a fetus is healthy or if medical intervention, such as delivery by surgical operation, is necessary.

Fetal monitoring module 210 may reside on one or more computing devices, such as, for example, computing device 22 described above with reference to FIG. 1. By way of example only and not limitation, computing devices may be a server, personal computer, desktop computer, laptop computer, handheld device, mobile handset, consumer electronic device, or the like. It should be noted, however, that embodiments are not limited to implementation on such computing devices, but may be implemented on any a variety of different types of computing devices within the scope of embodiments thereof.

As previously set forth, embodiments of the present invention related to computing systems for monitoring and displaying information regarding the health of mother and baby during pregnancy, labor and delivery. With reference to FIG. 2, a block diagram is illustrated that shows an exemplary computing system architecture for displaying and monitoring information during pregnancy, labor and delivery. It will be appreciated that the computing system architecture shown in FIG. 2 is merely an example of one suitable computing system and is not intended as having any dependency or requirement related to any single module/component or combination of modules/components.

The computing system includes one or more medical devices 205, fetal monitoring module 210, database 215 and graphical display 220. Discrete data elements are received from device 205. A medical device 205 may be any device, stationary or otherwise, that may be used to treat a patient in a hospital, doctor's office, etc. For exemplary purposes only and not limitation, medical devices include fetal heart rate monitors, blood pressure monitors, uterine pressure and contraction activity monitors, blood oxygen saturation monitors, maternal heart rate monitors, other monitors, ventilators, pumps (e.g., infusion pumps, balloon pumps), a patient's bed, sequential compression devices, electronic security devices, and the like.

Database 215 contains a variety of information data for the patient in a patient's electronic medical record (EMR). As utilized herein, the acronym “EMR” is not meant to be limiting, and may broadly refer to any or all aspects of the patient's medical record rendered in a digital format. Generally, the EMR is supported by systems configured to co-ordinate the storage and retrieval of individual records with the aid of computing devices. As such, a variety of types of healthcare-related information may be stored and accessed in this way. By way of example, the EMR may store one or more of the following types of information: patient demographic; medical history (e.g., examination and progress reports of health and illnesses); medicine and allergy lists/immunization status; laboratory test results, radiology images (e.g., X-rays, CTs, MRIs, etc.); evidence-based recommendations for specific medical conditions; a record of appointments and physician's notes; billing records; and data received from an associated medical device. Accordingly, systems that employ EMRs reduce medical errors, increase physician efficiency, and reduce costs, as well as promote standardization of healthcare. Graphical display device 220 may be a monitor, computer screen, project device or other hardware device for displaying output capable of displaying graphical user interfaces.

Fetal monitoring module 210 receives and displays data from a medical device for mother and baby during pregnancy, labor and delivery. Fetal monitoring module 210 may reside on one or more computing devices, such as, for example, computing device 22 described above with reference to FIG. 1. By way of example, computing device 22 includes a computer processor and may be a server, personal computer, desktop computer, laptop computer, handheld device, mobile handset, consumer electronic device, or the like.

Fetal monitoring module 210 comprises device data receiving component 215, stored information receiving component 230, graphing component 235, receiving component 240, determining component 245 and displaying component 250. Device data receiving component 225, receives discrete data from one or more medical devices 205. It will be appreciated that while fetal monitoring module 210 is depicted as being connected to a single medical device 225, fetal monitoring module 210 may receive discrete data from multiple medical devices including medical devices monitoring both a mother and her unborn baby.

The data received by data receiving component 225 includes device related output from the medical device. For example, data receiving component 225 may receive data from a fetal heart monitor, a maternal heart monitor, maternal blood pressure monitor, ultrasound, fetal scalp electrodes and a uterine pressure monitor. In one embodiment, the patient is continuously monitored and new data points are sent to the data receiving component 225 such that they may be plotted and displayed in a waveform quickly or in real-time.

Stored information receiving component 230 receives information from database 215 including a variety of information data for the patient in a patient's electronic medical record (EMR). By way of example, the EMR may store one or more of the following types of information: annotations regarding a patient's condition; patient demographic; medical history (e.g., examination and progress reports of health and illnesses); medicine and allergy lists/immunization status; laboratory test results, radiology images (e.g., sonogram, X-rays, CTs, MRIs, etc.); evidence-based recommendations for specific medical conditions; a record of appointments and physician's notes; billing records; and data received from an associated medical device.

Graphing component 235 converts the data received from medical device 205 into electronic waveforms that can be displayed as tracings or graphs. The term waveform refers to the shape of a graph of the varying quantity against time. Exemplary electronic waveforms for data from medical devices are shown in FIGS. 6-9. For example, as data comes in indicating a patient's heart rate, it is graphed as function of time in a waveform. In the exemplary waveforms, the newest data is plotted on the right side of the waveform. The prior data points are to the left of the newest plotted point. Exemplary data that is received and may be displayed in waveform includes, but is not limited to, fetal blood oxygenation saturation level, uterine activity, maternal heart rate, maternal EKG data, maternal blood pressure, fetal heart rate (beats per minute) and maternal blood oxygen saturation level. Fetal blood oxygenation saturation level (FapO2%) may include discrete data elements such as oxygenation saturation level, CO2 level, base excess and pH. Uterine activity may include discrete data elements such as uterine pressure and contraction activity of the uterine muscle (mmHG) and may be measured using tocodynamometry to determine progress of labor. Maternal heart rate is captured as beats per minute. Maternal blood pressure discrete data elements include systolic blood pressure (mmHG), diastolic blood pressure (mmHG) and mean arterial pressure (mmHG). Fetal heart rate includes beats per minute and may be captured by a monitor, ultrasound, and fetal scalp electrodes. Maternal blood oxygenation saturation level (SpO2%) may include discrete data elements such as oxygenation saturation level, CO2 level, base excess and pH.

Receiving component 240 receives inputs from a user utilizing a computing device 220 with a processor such as computing device 22 of FIG. 1. Receiving component 240 may receive a variety of inputs. For example, subcomponents of receiving component 240 receive inputs including requests to hide one or more of the waveforms, textual annotations, requests to hide one or more textual annotations, requests to save snapshots of a particular time period of the waveforms and associate the snapshots with other files, requests to view alerts, inputs of patient information and a variety of other inputs. These inputs will be discussed in more detail below. It will be appreciated that receiving component 240 comprises at least one subcomponent and may have any number of subcomponents. Alternatively, one or more subcomponents may be separate receiving components.

Determining component 245 makes a variety of determinations utilizing the input received by receiving component 210 and may have a number of subcomponents. For example, one subcomponent of determining component 245 determines to no longer display a waveform on the graphical user interface if a request to hide the waveform is received. One subcomponent of determining component 245 determines to hide annotations displayed if there has been a request to hide an annotation. Another subcomponent of determining component 245 determines an area of the one or more waveforms that is associated with the time of a selected annotation. It will be appreciated that determining component 245 comprises at least one subcomponent and may have a number of subcomponents. Alternatively, one or more subcomponents may be separate determining components.

Displaying component 250 utilizes a computer processor to display on display device 220 a variety of information. The information displayed regarding the patient's condition may come from medical device 205 and database 215. For example, subcomponents of displaying component 250 display graphical user interfaces including information on patient alerts, number of alerts, waveforms for one or more individuals, patient information and annotations. It will be appreciated that displaying component 250 comprises at least one subcomponent and may have a number of subcomponents. Alternatively, one or more subcomponents may be separate determining components.

Referring next to FIG. 3, a computer-implemented method 300 for determining and displaying only requested medical device waveforms for one or more individuals is shown. Computer-implemented method 300 is performed by one or more computer processors. At step 305, monitoring data from one or more medical devices for a first individual are received. In one embodiment, the first individual is a maternity patient. Exemplary monitoring data for the maternity patient includes heart rate data from a heart rate monitor, uterine pressure and contraction information from a uterine pressure and contraction activity monitor, blood oxygen saturation data from a blood oxygen saturation monitor(s) and blood pressure from a blood pressure monitor(s).

At step 310, monitoring data from one or more medical devices for a second individual is received. In one embodiment, the second individual is the unborn baby of the maternity patient. Exemplary monitoring data for the unborn baby of the maternity patient includes fetal heart rate from a fetal heart rate monitor and fetal blood oxygen saturation data from a blood oxygen saturation monitor. In one embodiment, the first individual may be an unborn baby of a maternity patient and the second individual is a second unborn baby of the same maternity patient.

At step 315, the data from the medical devices for the first and second individuals is displayed as waveform tracings. Graphing component 235 converts the data received from medical device 205 into electronic waveform tracings that can be displayed by displaying component 250 as tracings or graphs. The term waveform refers to the shape of a graph of the varying quantity against time. Exemplary electronic waveforms for data from medical devices are shown in FIGS. 6-9.

At step 320 of FIG. 3, a request to hide one or more of the waveforms displayed is received. In one embodiment, a user, such as a nurse or doctor, may request to hide one or more of the waveforms displayed for a first individual (e.g., patient, maternity patient or unborn baby of maternity patient) and/or second individual (e.g., patient, maternity patient or unborn baby of maternity patient). For example, and as discussed in more detail below, a user may choose to hide a waveform tracing for a maternity patient (e.g., waveform tracing not needed or is interfering with a waveform being displayed for the unborn baby). The request may be a request to hide or alternatively a request to view only certain waveforms.

At step 325, it is determined which waveforms to display based on the request from the user. For example, if the user has requested to view only the waveform of one unborn baby from a group of multiple babies, the determining component 245 would determine to display only the waveform of the one unborn baby and not the waveforms of the other babies. In another example, only the waveform tracing(s) of the maternity patient and not the unborn baby may be selected to be displayed. At step 330, only the waveforms as determined by determining component 245 to be displayed are displayed. Furthermore, it will be appreciated that waveform tracings for more than two babies may be displayed.

With reference to FIG. 4, a graphical user interface embodied on a computer-storage media showing data waveforms from one or more medical devices is shown. Display 400 includes waveform tracings for a single maternity patient 405 and her unborn baby. Waveform tracings for fetal heart rate 410, maternal blood pressure 415, maternal heart rate 420 and tocodynamonetry (TOCO) 425. Maternal blood pressure waveform 435, maternal heart rate waveform 420 and maternal uterine pressure and contraction waveform 425 are displayed for a first individual (maternity patient) along with fetal heart rate waveform 410 for a second individual (unborn baby of maternity patient). Display 400 also includes a display of the most recent numerical value of the data received from medical devices. Numerical measurements for patient 405 and her unborn baby for fetal heart rate 430 maternal blood pressure 435 and TOCO 440 are displayed on the graphical user interface along with the waveform of the data.

For example, with reference to FIGS. 4 and 5, a user has selected in FIG. 4 to hide the waveform 415 for maternal blood pressure as it interfering with fetal heart rate waveform 410 for which the clinician wants to see more clearly. The selection is received by receiving component 210 of FIG. 2. It is determined by a subcomponent of determining component 245 that waveform 415 is no longer to be displayed. Thus, in graphical user interface 500 of FIG. 5, waveform 415 is disabled and displaying component 250 displays the waveforms 410, 420 and 425 and not waveform 415.

With reference to FIGS. 6 and 7, graphical user interfaces embodied on a computer-storage media displaying continuous data waveforms from one or more medical devices for two or more individuals is shown. Display 600 includes waveform tracings for a single maternity patient 605 and her unborn triplet babies 610, 615, and 620. In one example, if one of the multiples appears to be in distress, the clinician may choose to view only the waveform of the unborn baby in distress and hide the waveforms for one or more of the other unborn babies. The selection to hide one of the waveforms is received by receiving component 240 of FIG. 2. It is determined by determining component 245 that only waveform 615 is to be displayed. Thus, waveforms 610 and 620 are disabled and in graphical user interface display 700 of FIG. 7 displaying component 250 displays only waveform 615 and not waveforms 620 and 625.

Referring next to FIG. 8, a computer-implemented method 800 for determining and displaying the area of a medical device waveform for an individual corresponding to the time of a textual annotation is shown. Computer-implemented method 800 is performed by one or more computer processors. At step 805, monitoring data from one or more medical devices for a first individual are received. In one embodiment, the first individual is a maternity patient. Exemplary monitoring data for the maternity patient includes heart rate data from a heart rate monitor, uterine pressure and contraction information from a uterine pressure and contraction activity monitor, blood oxygen saturation data from a blood oxygen saturation monitors and blood pressure from a blood pressure monitors.

At step 810, medical annotations related to the data received from the one or more medical devices is accessed and received. Medical annotations are accessed from database 215. The medical annotations may include textual notes, comments and observations by a clinician regarding are variety of things relating to the patient including the patient's condition, medical history, demographic information, test results and tasks and examinations performed for the patient. Common medical annotations utilized in labor and delivery may be displayed for selection by the clinician. In addition to accessing the medical annotations, any indication that one or more of the medical annotations should not be displayed is also accessed from database 215. The input of medical annotations is described below in more detail with reference to FIG. 9. At step 815, it is determined whether any of the annotations accessed from database 215 should be hidden. For example, a clinician may select to have certain annotations hidden at the time of entry or thereafter.

If it is determined that no annotations have been requested to be hidden at step 815, all related annotations are displayed at step 818. If it is determined that one or more annotations for the patient are to be hidden, at step 820, only annotations not identified to be hidden are displayed. At step 822, data from the medical devices for the first and second individuals is displayed as waveforms. As discussed above, the data from the medical devices is converted into electronic waveforms that can be displayed as tracings or graphs.

In one embodiment, at step 825, a user may select one or more of the annotations displayed at steps 820 and 822. The user may choose to view the related portion of a waveform tracing for the annotation by selecting or clicking on the annotation. At step 830, the associated area of one or more displayed waveforms is determined. For example, if an annotation was documented as occurring at 8:00 p.m., the area of one or more of the associated waveform for 8:00 p.m. for the individual is displayed. This may be done on a waveform with the most current data or in a separate waveform with historical data. In one embodiment, the current data waveform is displayed simultaneously with a historical data waveform for the individual and the area. This is described below in more detail with reference to FIG. 10.

As shown in FIG. 9, an exemplary graphical user interface 900 for allowing a user to input medical annotations for a labor and delivery patient is shown. As depicted in FIG. 9, the annotation box 905 is displayed along with waveform of medical device data for the maternity patient and unborn baby. Textual annotations may be input by a clinician into text box 910. Common medical annotations 915 for labor and delivery that may be selected by a clinician include, but are not limited to, increase IV fluids, O2 8-10 L/Min per FM, oxytocin infusion discontinued, oxytocin infusion increased, primary provider at bedside, primary provider notified, pushing, tocolytic administration, patient turned to left side and vaginal examination. The clinician may select sign button 925 to send and store any annotations made. The annotations along with the associated time and date when the annotation was made are then stored in database 215.

With regard to FIG. 9, a user, such as a nurse or doctor, may enter or select an annotation and choose to have it hidden for privacy reasons by selecting check box 1520. For example, sensitive information about the maternity patient, such as past pregnancies, terminated pregnancies, medical conditions (e.g., sexually transmitted diseases) and demographic information (e.g., weight) may be selected to be hidden by the clinicians so that non-medical personnel in the patient's room cannot see the annotations. Non-medical personnel may include persons in a non-medical care giving role such as family and friends of the patient and personnel of the healthcare facility that have no need to know the medical information contained in the annotation. This annotation and the selection to “hide” the annotation are stored in a database, such as database 215.

With reference to FIG. 10, an exemplary graphical user interface 1000 for displaying waveform data and related medical annotations for a patient is shown. As depicted in FIG. 10, medical annotations 1005 are in an area on the user interface 1000 separate from the display areas of current 1015 and historical 1020 waveform tracings for the patient. The current waveform tracing 1015 has the most recent data for the patient from one more medical devices. Historical waveform tracing 1020 has historical data for the patient from one or more medical devices for a specific time period. In this example, the exemplary specific historical time period for the patient is from 6 a.m. to 7 a.m. on Oct. 27, 2007. Medical annotations 1005 for the patient are listed from the most recent to the oldest. For example, medical annotation 1010 of maternal blood pressure and maternal heart rate is the most recent medical annotation for the patient.

Referring next to FIG. 11, an exemplary graphical user interface 1100 for displaying current, historical and archived waveform tracings along with medical annotations for a patient is shown. As depicted in FIG. 11, medical annotations 1105 are in an area on the user interface 1100 separate from the display areas of current 1120, historical 1125 and archived 1130 waveform tracings of data for the patient from one or more medical devices. The time frame on a waveform associated with a selected medical annotation is displayed. The current waveform tracing 1120 has the most recent data for the patient from one more medical devices on Oct. 27, 2007. Historical waveform tracing 1125 has historical data for the patient from one or more medical devices for a specific time period. In this example, the exemplary specific historical time period for the patient is from 6 a.m. to 7 a.m. on Oct. 27, 2007 which is an earlier time period of the same visit of the patient as the current 1120 waveform tracing. For example, the same visit of the patient may be an admission to a hospital or a doctor's visit. Archived waveform tracing 1130 is for a different visit of the patient on Oct. 13, 2007. In this example, the archive view includes annotations 1115 and waveform tracing 1130 for a previous hospital admittance or doctor's visit for the patient.

As described with reference to FIG. 8, a user may select one of the annotations 1110 and 1115 to view the related portion of the corresponding current 1120, historical 1125 or archived 1130 waveform tracing. For example, if annotation 1110 (made at 8:10 a.m. on Oct. 27, 2007) is selected by a user, the associated time period (8:00 to 9:00 a.m. on Oct. 27, 2007) on of the historical waveform tracing 1125 is displayed. An identification 1135 of the time corresponding to the time of the annotation (8:10 a.m. on Oct. 27, 2007) is displayed on waveform tracing 1125. If the user selects annotation 1115, the associated time period of the archived annotation is displayed on the archived waveform tracing 1130. An identification 1140 of the time corresponding annotation time is displayed on archived waveform tracing 1130.

Referring next to FIG. 12, a computer-implemented method 1200 for displaying patient alert information based on location is shown. Computer-implemented method 1200 is executed by one or more computer processors. At step 1205, monitoring data from one or more medical devices for a patient is received. In one embodiment, the patient is a maternity patient or an unborn baby. Exemplary monitoring data is described above.

At step 1210, it is determined that the monitoring data received satisfies a rule that would trigger an alert. Exemplary rules include determining data for a heart rate is outside of a specified range, a patient's blood pressure outside of a specified range, uterine pressure and contraction data outside of a specified range, blood oxygen levels outside of a specified range and other data outside of a specified range. At step 1215, it is determined whether the location of the device displaying patient information is to be alerted. The determination is based on the physical location of the device and is not dependent on which user is logged on or signed into the device. In some instances, based on location of the device, all alerts for all patients are to be displayed. For example, a nurse manager may want to see all alerts for all patients. In some instances, based on the location of the display device, all alerts for only some patients are to be displayed. For example, if a floor is divided into multiple nursing units, each nursing unit including four patient rooms, only alerts for the patients in the patient rooms of the nursing unit will be displayed on devices located in the nursing unit. In some instances, based on the location of the display device, no alerts are to be displayed and only the number of alerts is to be displayed. For example, as the caregivers in the operating or c-section room cannot leave to respond to any alerts, an operating or c-section room may be designated as a location to display only the number of alerts and not the actual alert information.

At step 1220, if it is determined the display device location is not to display the content of the alerts; only the number of alerts is displayed. Alternatively, no information is displayed. At step 1225, if it is determined that the display device location is to display the alerts and alert content, the alert, alert content and total number of current alerts are displayed. In one embodiment, the alert and alert content are displayed at the display device location.

Referring next to FIG. 13, an exemplary graphical user interface 1300 displaying waveform tracings of monitored data for multiple maternity patients 1315. Based on the location of the display device being utilized to display graphical user interface 1300, all alerts for all patients are displayed. It can be seen in exemplary graphical user interface 1300 that exemplary patients Anna Long 1320 and Jane Cooper 1325 are highlighted and are in alert. In addition, the total number of alerts 1305 is displayed on the graphical user interface so that a user can see how many alerts there are and identify necessary personnel to address the alerts. In this example, there are a total of two (2) 1310 patients in alert. A user may choose to view only waveform tracings for those patients with alerts. In one embodiment, this is done by selecting alert button 1305.

Referring next to FIG. 14, an exemplary graphical user interface 1400 displaying waveform tracings for patients with alerts 1425 is shown. Graphical user interface 1400 includes the waveform tracings for fictitious patient Michelle Bailey 1410 and Anna Long 1415. A user may select to suspend, cancel and/or enter a textual annotation 1425 for the patient regarding the alert from graphical user interface 1400. The total number patients with alerts 1420 is displayed on the graphical user interface.

FIG. 15 is an exemplary graphical user interface 1500 allowing a user to flag and store a portion of a waveform tracing 1505. Graphical user interface 1500 includes multiple waveform tracings for fictitious patient Michelle Bailey. A user, such as a nurse or clinician, flags a portion of the waveform tracing 1505. The user may then select to associate the portion of the waveform tracing 1505 with additional information for the patient such as textual entries, pictures, video, sonogram photographs, sonogram video, laboratory results and other stored files for the patient that relate to the time period of the waveform tracing 1505. For example, the portion of the waveform tracing 1505 may be for the period while a sonogram was being performed for the patient.
